Abstract

Time domain reflectometry and conventional AC-impedance spectroscopy were combined to investigate the impedance response of fiber-reinforced fresh-cement composites over a broad frequency range (0.1 Hz to 1 GHz). With proper attention to inductive effects at high frequency, conventional AC-IS can be employed to evaluate important fiber dispersion issues (fiber orientation, segregation, and clumping) in fresh-cement matrix composites.
